Ton/Ill, whom it may concern:

Be it known that I, EDWARD C. MEAD, a

- citizen of the United States, residing atElkplaced in a recumbent, reclining, or sitting position, as desired, may be easily lifted or hart, Indiana, have invented certain new and useful Improvement s in Invalid-Beds, of which the following is a specification.

g My invention relates to improvements in cots or beds for the use of invalids; and the object of the invention isto provide a construction in which the patient may be readily supported free from the cot or bed proper, and will permit of changing the bedding and allowingafreecirculation of air. A further object is to provide a cot or bed on which the patient can be easily handled and his position changed as desired without the necessity ofhis being lifted by the nurse.

A still further object is to improve the various details of-construction in the respects hereinafter described.

The invention isillustrated in the accompanying drawings, in which' Figure. 1 is aside view of the cot or bed. Fig. 2 is a plan View. Fig. 3 is an end view.

Fig. 4 is a sectional view taken near the center. Fig. 5 is a detail view, and Fig. 6 is a detail view of a modifiedform of foot-rest.

Referring by reference characters to these figures, the ordinals 2 designate the side rails or main frame of the cot and to which the legs 1 1 are attached,these being in turn connected by braces 33, so that the whole forms a rigid frame. Connected to and form a part of the device for raising the patient and supporting him free from cot or bed.

other suitable support 10, which rests against the top of the side rail 6 'or preferably engages pins on the said rail, as shown, and holds the arms or standards in an upright -way when not in use.

Attached to-each standard 9 is a brace or position. This brace-or-support 10 is so constructed that it can be released and the arms.

or standards 9 folded down at the sides and out of the way. An arm-rest 11 is hinged to the head-sec-tione oneach side, at 12, and an arm or standard 13 is attached to each side rail 20f the main frame of cot or bed and connected to the corresponding arm ll b any suitable connection, preferably pin-and-s 6t,o as at 13 The arms 13 are a part of the device for raising and supporting the patient off from the bed and are operated and held in position by the segmental arms 14, said arms working through guides 14 on the sides of frame 2 and connecting with and being actuated by the lever device shown in detail in Fig. 4. Thearm 13 also acts as a support for the arm-rest 11, the end of the arm-rest being suitably notched or bifurcated to pass over the end of the standard 13.

The foot-section 16 of'the cot is adjustable and is hinged to the main frame of the cot at 17. It ma'y be raised or lowered to any desired position and held by the segmental notched rest or support 18, said circular notched rest or support being hinged to the foot-section 16 and engaging afsuitable crossbar connecting the two foot-legs of the cot.

Arms .20, pivotally connected to the legsection; complete the device for raising and lowering the patient and sup orting him free from the cot or bed. Attac. ed to each arm is a notched brace or other suitable support 21 for holding the arms 20 in a suitable position and which brace or support 21 engages the section -1 6. and may be released to allow the arms 20 to be folded down and out of the p A foot-rest 23 is attached to the foot-section 16 by arms 24 and is held in an upright position by the brace or support 25. This foot-rest is so constructed that it can be swung down at the end of the foot-section 16when not in use. In the center of the central section isa trap or door26, which is opened and closed by the crank-shaft 56, j ournaled at 57 and having a handle 58.

Attached to the central section is a device for swinging a chamber under the trap or door 26. -This device consists of the long arm 27, havingat its inner end a suitable device 28 for holding the chamber. This arm is attached to the cot by means of a hanger 29, pivotally engaging a bearing-bracket 30,-

to which hanger is rigidly attached a bar, 3 1.

- The long arm 2.7 is pivot ally and slidably at- IIO 2o book-rest, &c.

tached to the bar 31 by means of a slide 32.

The arm 27 is pivoted upon a bearing in the slide 32, so as to give the long arm an upward and downward motion. At the outer end of 5 the arm 27 is a spring-latch 33, which actuates'a pin engaging notches in the bar 31 ,and a downward extension therefrom, this latch device holding the chamber device in the desired osition. By means of this device the TO cham er is swung under the trap or door.

The "long bar 27, operating by means of the slide 32 or the bar 31, together with the bear- 1 brought to the proper position under the trap r 5 and raised to the desired position for use, and

2 5 placed across the topsof the brackets as a support for the patients limbs. .The armrests 11 in Fig. 1 also have similar holes or bearings 11 for receiving pins on a bar to act as a support for the arms of the atient.

In Fig. 3 is shown in detail t e device by which the head-section of the bed is raised and lowered to the desired position. It con "sists of a hand-lever 38, connected to a lever 39, pivoted at 39 having its free end 40 con- 3 5 nected by a link 41 to one member 41 of a toggle-joint 4'1 and 42, the latter member being connected to a cross'bar of the headsection. The parts 41 and of the toggle are connected by a pin held in place by a 40 spring 41 so that the head-section canbe detached from the lever when desired, this being shown in Fig. 5. The handle 37 of the hand lever preferably slides down upon the part 38 when not in use and may be pulled out to 44. give a greater leverage as desired. By this means a downward motion of the lever 38 raises the head-section very easily. The lever 38 engages the notched holder or upright 4 (shown in Fig. 1) and holds the head-section' in any desired position. This device rests upon a cross-bar 43, which cross-bar is supported by the brace 3. (Shown in Fig. 1.) The lever 39 is pivotally mounted upon a bracket. projecting up from the cross-bar 43, so as to swing on an axis parallel to the axis of the head-section.

Fig.4 shows a similar lever device for oper ating the central uprights or standards 13, (shown in Fig. 1,) 44 45 being the handle and lever proper and 46, 47, 48, and 49 being the arms and toggle-links. This device rests upon the floor and is attached to the braces 3 (shown in Fig. 1) by the supports 51. The arm 49 is suitably attached to a cross-bar 52, which cross-bar connects the segmental arms 14. (Shown in. Fig. 1.) Attached to the cross-bar 52 is a tongue or lug 53,which operates in the slides or guide 54 for the purpose of holding the arms 14 in a central position. In the outer end of the tongue or lug 53 is a pin to prevent it slipping out of the slide or guide 54. The handle or lever proper, 44 45, engages the notched holder 5 (shown in Fig. 1) and holds the uprights or standards 13 in the desired position.

When it is desired to raise the patient from the cot for the purpose of changing the bedding-er te allowwa nneulation of air around the patient, a suitable support or hammock made of heavy canvas or other suitable material is used. This hammock deviceis attached at its head-end to a suitable poleor top ofthe arms or standards 9, which are raised to a vertical position. The head section of the bed is then raised so as} to bring the patient to a sitting position, when the hammock is folded down behind the pameans to the top of arms 13. The headsection of the bed is then lowered, and by a downward motion of the lever 44 45 the body of the patient is raised from the bed. The lower end of the hammock is then hooked or fastened to the top of arms 20, and these arms are raised to an upright position, when the patient will besupported entirely free from the bed. To replace patient on the bed, the operation is reversedu By this device the patient can be readily handled by one nurse and without jarring the patient. When the arms 13 are raised to an upright position, they stretch the head-section of the hammock. and when the arms 20 are raised the foot-section of the hammock is stretched.

porting the hammock, they are disconnected from the arm-rest 11. With" this cot or bed sectional springs and mattresses .may be tresses and springs having openings corresponding to the door 26, and the. portion of springs and mattresses covering door 26 may be permanently attached to the door or trap.

1n the modified form shown in 6 I otally connected together by a cross-bar 21 and to the leg-section, serving tocomplete the device for raising and lowering the patient and supporting him free from the cot or bed. Attached to the standard 19 is a spring, brace, or other suitable support 22 for holding the standards 19 and 20 with their connecting cross-bar 21 in an upright position, and which spring, brace, or support 22 rests upon the top of section 16 and may be released to allow the'standards 19 and 20, with their connecting cross-bar 21, to be folded down and out of the way when not i. in use.

When the arms 13 are to be used for supused as desired, the central section of mat bar, which rests in notches or holes 9 in the tient and hooked or fastened by suitable.

provide standards or uprights 19 20', piv- Having thus described my invention, what I claim is a main frame, a head-section pivoted thereto with means for operating it, standards pivotally connected-to said head-section and adapted for engagement with a suspending device, and means near the center of the bed for drawing upon said suspending device to lift the patient, substantially as described. 3.
